Adding a Blade Scan Control Point

When you add a Blade Scan control point, the center of the spherical control point is the leading edge (LE) or trailing edge (TE) point, depending upon the concave (CC) or convex (CV) section you are measuring.

1. Click the Add button in the Control Points area in the Blade Scan dialog box. The Control Point dialog box appears:
